HEEL sm'r FITTING momma Filed Nov. '7, 1925 9 Sheets-Sheet 9 knife operable after the breast cutting knives Patented Dec. 10, 1929 UNITED STATES PATENT OFFICE WILLIAM C. STEWART, OF SWAMPSCOTT, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY Application filed November This invention relates to the manufacture of shoes and isdisclosed as embodied in a heel seat fitting machine arranged to trim the peripheral portions of the heel seats of shoes to which wood heels are subsequently to be attached.

In the manufacture of shoes to which wood heels are to be attached it is usual, prior to the attachment of the heels, to trim away the surplus material from the periphery of the heel seat portions of, the soles of the shoes so as to shape the soles to fit the concave heel seat surfaces of the wood heels. lt is an object of the present invention to provide a machine which will perform this operation in a satis factory manner and with a minimum requirement of skill on the part of the operative.

The herein disclosed machine not only fulfills these qualifications but is simple in construction, rapid in operation, and is adapted for use upon shoes to which any of the various styles of wood heels are to be attached. With these objects in view the invention is herein disclosed as embodied in a heel seat fitting machine having knives movable transversely of the sole of the shoe to be operated upon, from the edge of the sole inwardly, to make the heel breast receiving cuts, and having a have been withdrawn to complete the cutting operation by trimming the peripheral portion of the heel seat of the sole of the shoe from the heel breast receiving cuts toward the rear, thus removing an approximately horseshoe-shaped chip.

Features of the invention include mechanism for moving the knives which makethe breast cuts alternately in either a straight path to fit the shoe for a full Louis heel or,.in--- a curved path to fit the shoe for a Cuban heel or for any other heel which requires a concave breast cut; an organization of the ma-- chine by which the heel seat fitting knife is moved rectilinearly substantially at right angles to the sole of the shoe to bring its cutting edge into engagement with the sole at the heel breast line after the heel breast receivingcuts have been made, and for thereafter causing relative movement of the knife and the shoe to cause the knife to trim the 7, 1923. Serial No. 673,379-

peripheral portion from the heel seat of the sole of the shoe; means for insuring an effective cutting action of the knife illustrated as comprising a roll engaging the sole of a shoe and operative to force the sole toward the cutting edge of the knife; a crease plate operative to enter the rand crease of the shoe to deflect the edge portion of the heel seat of the sole of the shoe away from the shoe upper after the heel breast receiving cuts have been made but before the trimming of the periphcry of the heel seat; and a crease plate movable into the rand crease of the shoe before the making of the breast cut and out of the rand crease after the making of the breast cut but before the trimming of the peripheral portion of the heel seat.

. Wit-l1 the above and other objects and features in view, the invention will now be described with reference to the accompanying drawings, which disclose a preferred embodiment thereof, and pointed out in the claims.

Figs 11, 12 and 13 are diagrammatic views indicating the sequence of operations of the machine and showing in Fig. 13 ashoe upon which the heel seat fitting operation has been completed.

The illustrated machine is of a type arranged to remove a horseshoe-shaped strip of material from the heel seat of a shoe to which a wood heel is to be subsequently attached, the machine being provided with a pair of knives moving transversely of the sole of the shoe to make the heel breast receiving 5 cuts at the forward extremity of the heel seat and with a trimming knife arranged to move from the heel breast line rearwa-rdly, after the heel breast receiving cuts have been made, to complete the operation, the peripheral'portion of the heel seat of the sole being deflected away from the shoe upper while these cuts are made so that it may be trimmed from the sole by a rectilinear movement of the trimming knife.

The illustrated machine is provided with a column 16 having horizontal ways 18 in which is mounted a ram or sliding head 20. Column 16 serves also as a support for a motor 22 and is provided with suitable bearings for a main power shaft 24-and a, countershaft 26.

Mounted on vertical pivots '28 (Figs. 1, 2'

and 7) near the top of the column of the machine is-apair of bell crank levers 30, each carrying at its forward extremity'a rubber 25' gripping jaw 32. Thesejaws 32 constitute work supportingand clamping means and are arranged to grip a shoe 31 mounted on a last 33 between them, as indicated in Figs. 2 to 7, and for convenience in operating them a treadle controlled link and lever system is provided. A sole .35 has already been attached to the shoe 31 and a breast covering flap '37 (Figs. 2 and 13) cut up from the sole. The jaw "operating means comprises a treadle 35 34 (Fig. 1) fulcrumed at 36 to the, base of column 16 and provided with a spring 38 tending to hold it in elevated position. A

' link 40' is connected at its lower end to treadle 34 and at its upper end, at 41 (Figs. 1, 2, and 7), to' the forwardly extending part of a bell crank lever 42. The bell crank lever 42 'and a corresponding vertical arm 43 (Fig. 2) are clam ed on a transverse shaft 44 having a bearing m the column 16. The arm 43 and the upwardly extending arm of the bell crank lever 42 bear at 46 against the outwardly extending arms of the corresponding j aw-carrying bell crank levers 30 so that when treadle 34 is depressed, the outwardly extending arms of bell crank levers 30are moved forwardly and their forwardly extending arms, which carry the rubber jaws 32, move in- Qwardly to grip the work. A pawl 48 (Fig. 1) is carried by treadle 34 and co-operates with a rack 50 to hold treadle 34, and therefore jaws 32,in whatever position they may be placed. Pawl 48 is provided with a forwardly extending tail52 which is engaged by a compression spring 54 which tends to hold pawl 48 in engagement with rack 50 but permits its ready release by the foot of the operative. To facilitate proper positioning of the work in the machine, a' back gage 60 '65 (Figs. 1, 7, and 11) which may be adjusted or controlled in any usual or convenient manner is carried to the rear of jaws 32.

As illustrated, gage 60 is connected at 62 (Fig. 11) to a slide 64 (Figs. 1 and 2), mounted on ways formed in or carried by column 16, and provided with a rack 65 operatively engaged by a pinion 66 mounted on a shaft 67 which carries also a hand lever ".68 by means of which gage 6O may be adjusted. Shaft 67 may be secured in adjusted position by any suitable devices, and an indicator may be provided to indicate the position of, gage 60. After the shoe 31 has been positioned in the machine with the rear of its counter portion against back gage 60 and has been securely gripped between jaws 32, the machine is operated to make the heel breast receiving cuts to form shoulders 72 (Fig. 13) against which the breast of the heel is subsequently to be positioned. For this purpose the machine is provided with a pair of breast cutting knives 76 eachof an L-shaped cross section and having two cutting edges substantially at right angles to each other (Figs. 2 to 6 and 11). These cutters 76 are'each carried by a block 77 mounted for sliding movement in a way 78 pivoted at 80 to the upper endof a double armed lever 82 (Fig. 2), each guide or way 78 being provided with a tapered extremity forming a crease plate or guard 84 arranged to enter the rand crease of the shoe to protect the upper and support the edge 85 of the sole 35 during the making of the heel breast receiving out. These levers 82 are pivoted as at 86 (Fig. 3) to collars 87, 88 carried by the upper end of a post 89 mounted for vertical sliding movement in ways 90 (Fig. 1) formed on or carried by column 16. I A stop 92 positively limits downward movement of post 89 while a compression spring 94 supported by a bracket 96 carried by column 16 has its upper end housed in a socket 98 formed in the lower end of post 89 and thus tends to elevate the latter. Fulcrumed also at 86 to the upper end ofvpost 89 is a pairof double bell crank levers 100 (Figs. 2 and 4),

each of which is connected at its upper end by a pair oflinks 102 with the corresponding block 77 to which one of the knives 76 is rigidly secured. A compression spring 106 (Figs. 4, 5, and 6) bears at one end against each of the levers 82 and at the other end againstthe corresponding lever 100 keeping them normally separated. A threaded rod 108 (Figs.'4 and 7) is secured to each of the levers 82 and is provided with a nut 110 bearing against lever 100, which thus limits the relative movement of lever 82 and bell crank lever 100 under the action of spring 106. Tension springs 109 (Fig. 3) tend to move the inner ends of ways 78 downwardly to a position determined by arms 111 which are carried by ways 78engaging the levers 82. The approximately horizontally extending arms of bell crank levers 100 are connected by a lowers rods 112 and roe 's levers 82 pair of vertical rods 112 to a horizontal rod 114 (Fig. 1) carried by the forward extremity of a lever 116 fulcrumed at" 119 to column 16. A link 120 connects lever 116 to a treadle 118 fulerumed to the base of column 16. Link 120 is rovided with a collar 122 which is engage by the upper end of a spring 124 housed in a socket formed in the lower portion of the post 89, spring 124 thus tending to elevate rods 112. A second collar 128 car ried by link 120 limits this elevating movement.

\Vhen treadle 118 is depressed, the forward end of lever 116 is swun downwardl This rom the position of Fig.3 to the position of Fig. 4, crease plates 84 entering the rand crease of the shoe and thereafter preventing further inward movement of levers 82 about pivots 86. During this period, post 89 is sustained against downward movement by spring 94. When crease plates 78 can no longer move toward each other, further depression of treadle 118 results in the bodily downward movement of fpost 89 with the consequent compression 0 spring 94. During this period, creases plates 78 rock about the rand crease of in Fig. 5. (When post 89 brings upagainst stop 92, continued depressionof the treadle 118 and of rods 112 rocks bell crank levers 100 about their pivots 86, compressing s rings 106 and forcing knives 76 into the e ge 85 of the sole 35, with an inward andupward movement, to the ositionrindicated in Fig. 6. When the tree 1e is released, the reverse movement takes place.

It will be noted that the movement of the knives 76, as just described, is such as to make a straight cut into the sole of the shoe. In fitting heel seats for shoes which are to be provided with Cuban or other straight heels, as distinguished from Louis heels, it is desirable that the breasting cuts be curved instead of straight so that they may correspond to the concave breast of those heels. With this in view, mechanism is provided for swinging the breast cutting knives 76 and a portion of their 0 eratin mechanism about a vertical axis as t ey ma e the breast cut. For this purpose, collars 87 and 88 are rotatably secured to 0st 89, so as to be caable of rotation a out the axis thereof.

ach of these collars is, provided with-a air of lugs 140 (Figs. 1, 3 and'?) between w ich the forward ends of links 142 are secured to gimbal joints 143 (Fig- 3). The other ends of links 142 are connected by universal connections 144 to the lower ends of levers 146 (Figs. 1 and 2), the u per ends of which are pinned to a cross sha t 148 journaled in column 16. A rod 150 is pivoted at 152 to rod 120 so'as to move downwardly with the latter when treadle 118 is depressed. At its upper end rod 150 passes through a slot in nary portion of 1e shoe to the position illustrated.

a link 154, which is connected at one end to the lower end of one of the levers 146. A pair of lock nuts 156 prevent the escape of rod 150 through the slot in link 154. Thus the connection between rod 150 and link 154 has a certain amount of lost motion so that link 154 will not be affected by the prelimithe downward movement of treadle 118. The other end of link 154 is provided with a head slidable in a curved slot 158 formed in a guide member 160 pivoted at 162 to column 16 and adjustable by means of a bolt 164 passing through a slot in the guide member. When in its extreme position. as shown in Fig. 1, the slot 158' of guide member 160 is positioned on the are of a circle having as its center the pivotal connection of links 142 and levers 146. When adjusted, however, in a clockwise direction (as viewed in Fig. 1) from that position, the downward movement of link 154, as treadle 118 is depressed, forces the lower end of levers 146 rearwardly thus moving links 142 rearwardly androtating collars 87 and 88 and the parts of the machine carried by them. This movement does not'take place, on account of the lost motion of rod 150 and link 154, until knives 76 are just entering the edge of the solel As they make their cut, the are thus rotated about a vertical axis an form the desired arcuate breast cut. The degree of curvature of the cut can of course be varied by the suitable adjustment of guide member 160 and, as before noted, whenthat member is in the position of Fig. 1, the cut made will be straight instead of curved. A spring 165 (Fig. 1) may be provided to ensure the return of the forward end of link154 to its elevated position when treadle 118 is released.

After the breast cuts have-been made in the sole and knives 76 have been returned to theirinoperative position, the machine is operated to trim the peripheral portion of the u heel seat so as to remove a horseshoe-shapedj' strip of material to form a bevel 170 (Figig ii o 13) in order to finish the heel seat operation. This .trimming operation is er-r. formed by the rearward movement of a knife 180 (Figs. 3 and 7) provided with a straight cutting edge 182, which, as the knife is moved rearwardly, enters upstanding corners 183 of, the edge portion 85 of the sole 35 at the location of the breast cut, the sole at that time being in the condition indicated in Fig. 12. This knifeis carried by the ram 20 (Fig. 1), which is given a reciprocating movement by power-operated mechanism under the control of a lever 184 fulcrumed to the column 16 at carries a clutch, which mayconveniently be of the Horton type, having a dog controlled by arm 194 of lever 184. When it is desired to connect the clutch so'as to operate the knife carrying ram 20, the operator pushes in the rod 188 to bring lever 184 to the position shown in Fig. 1. As long as lever 184 remains in the position indicated in Fig. 1, the clutch transmits power, but when the upper end of lever 184 is moved forwardly by the spring 190, the clutch, upon the completion of the revolution upon which it is then'en'gaged, is disconnected. From the clutch power is transmitted through gearing 196 to. shaft 26, the latter carrying a segmental flange 198 arranged to cooperate with a roll carried by the upper end of lever 184 to hold that lever in the position shown in Fig. 1 during something more than a complete revolution of the lower one of the gears 196 and shaft 24. Thus as soon as the machine has been started, the operator may release push rod 188 and the lever 184 will be held by the flange 1.98 to keep the clutch in engagement so that the machine will neverthelesscomplete its cycle of operation which requires two complete revolutions of shaft 24.

Shaft 26 carries upon it cams 200, 202 and 204. A roll 206 carried by a bell crank 'lever 208 engages the track of cam 200. The upper end of lever 208 is provided with a rack segment 210 co-operating with a rack bar 212 carried by ram 20 so that as cam 200 rotates the ram will be moved rearwardly, will then come to rest and will ultimately be moved back to its original position.

, at 230 to ram 20, one arm pf the bell crank lever co-operating with link 226 to form a toggle mechanism. The other arm of bell crank lever 228 is connected b a link 232 to a block 234 fastened to a 1'0 236 mounted for .sliding movement on ram 20. Block 234 is provided with a lug 237 extending into the path of movement of the upper end of a lever 240 fulcrumed to column 16 and provided at its lower end with a 'roll co-operating with the track of cam 202. The upper end of lever 240 is provided with a pair of contact members 242 and 244, the latter being in the form of a screw by means of which the distance between the contact members may be adjusted.

Thus it will be seen that when lever 240 is rocked under the control of cam 202 andthe ram is reciprocated under the control of cam 200, theupper end of the lever 240 will move forward until contact member 242 engages lug 237 after which rod 236 will be moved forward and plunger 218 will be moved up and held in its upper position, cam

'knife 180 which thus moves in a rectilinear path substantially at right angles to the tread surface of the sole of the shoe to be operated on as it is brought into engagement with the sole at the heel breast line when plunger 218 is depressed and, during the sub sequent rearward movement of ram 20, performs the trimming operation.

In order to support the edge of the sole during the trimming operation, the machine is providedwith a plate 245 (Figs. 1, 3, and 12) mounted for sliding movement in ways 243 (Fig. 3) carried by column 16 and connected by a link 246 to' the upper end of a bell crank lever 247 (Fig. 1) fulcrumed to column 16 and provided at its lower end with a. roll engaging the track of cam 204. At its forward end plate 245 is provided with a horseshoe-shaped opening 248 (Fig. 2), the edge of this portion of the plate being beveled so as to enter the rand crease of the shoe and force the edge portion of the sole 35.11pwardly, as illustrated in Figs. 3 and 12 thus lifting the corners 183 into the path of the knife edge 182. For the purpose of ensuring efiective control of the stock ofthe shoe sole during the trimming operation, a holddown in the form of a toothed presser roll 250 (Figs. 7 and 8) is provided. This roll travels just to the rear bf the knife 180 and durin the trimming operation is rotated towarg the knife (counter-clockwise as indicated b the arrow in Fig.7) at a speed slightly aster than it would have if it simply rolled idly along the stock, so as to hold the stock pressed toward the knife ed c. This roll 250 is keyed to a shaft 252 (see ings 253 carried by a spring-pressed plunger 254 housed in lunger 218. As illustrated in Fig. 8, a suita le friction device 251 may be used to prevent undesired movement of shaft 252.. Thus roll 250 is held firmly in engagement with the sole of the shoe operated upon to depress the center of the heel seat out of the path of movement of the knife but may yield to compensate for variations in the thickness of the sole. In order to obtain the desired rotary movement, a pair of rack bars 256 and 257 Fig. 9), held in rigid relation to one another y brackets 261, are pivoted at? 255 to column 16 (Figs. 1 and 9) co-operating with pinions 258 and 259 mounted loosely upon shaft 252. Finned to shaft 252 is a. ratchet 260 (Figs. 9 and 10) co-operating with ig. 7) mounted in bear-' apair of spring-pressed pawls 262, 263 carried by pinions 258 and 259 respectively. Since the pinions 258 and 259 are slightly smaller than roll 250, the latter will have a peripheral velocity somewhat greater than it would have if rolling idly on the shoe sole and therefore will tend to feed the stock of the sole toward the cutting edge of knife 180 during the trimming operation. Moreover, this pawl and ratchet mechanism causes roll 250 to feed the severed chip upwardly and forwardly away from and out of the way of the cutting edge of knife 180 during the forward movement of ram 20, the roll rotating in the same direction (counter-clockwise as viewed in Fig.7) during both the forward and rearward movement of ram'20.

While the operation of the herein disclosed machine has been pointed out in connection.

with the description above, it will now be reviewed as a matter of convenience. The operative first locates the work, which consists of a shoe upon a last and having its outsole but not its heel attached, with its counter portion between the jaws 32 and with its back seam against gage'GO. He then depresses the treadle 34 which causes the jaws 32 to grip the shoe, pawl 48 latching the treadle in depressed position. He next depresses treadle 118 which causes crease plates 84 and knives 76 to swing toward the shoe until crease plates 84 enter the rand crease of the shoe. Then the knives 7 6 and crease plates are rocked downwardly about the rand crease as an axis and the knives 7 6 are moved inwardly and upwardl making the heel breast receiving cuts in the sole (as in Fig. 6). During this cutting operation the knives 7 6 will move in a straight line or will be rotated about a vertical axis forward of their cutting edges according to the adjustment of guide member 160. After the heel breast receiving cuts have thus been made, treadle 118 is released and the rod 188 is pushed rearwardly tripping the clutch and causin the power-operated parts of the machine to become effective. The ram 20 thus moves forwardly to the position indicated in Fig. 1 and the cam-operated lever 240, straightening the toggle 226, 228, causes the plunger 218, carrying knife 180 and the roll 250, to move downward to bring the cut ting edge 182 of the knife 180'into engagement with the sole of the shoe ad'acent to.

and just forward of the location 0 "theheel breast cuts which have been previousl made. While this is taking place, crease p ate 245 moves forward and enters the rand crease of the shoe, deflecting the peripheral portion of the heel seat of the sole of the shoe upwardly, as slrown in Fig 12, into the path of the horizontally moving knife edge 182. The ram 20 is nextrnoved rearwardly causing knife 180 to trim ofl" the upwardly deflected periphery of the heel seat portion of the s'ole. During this operation roll 250 is positively rotated in a counter-clockwise direction, as viewed in Fig. 7, at a speed slightly greater than it would have if rolling idly so as to tend to force the sole toward the cutting edge of the knife 180. After knife 180 has finished its cutting operation and has passed the rear of the work, cam-operated leven-240 breaks the toggle 226, 228 so that the plunger 218 is elevated, raising the knife 180 and the roll 250 with it as the machine comes to rest. Crease plate 245 is withdrawn by the min 204 at the proper time and treadle 34 may then be released and the shoe removed.
